Lens 5.2 adds Apple M1 support, Monaco integration, and smoother user experience

Edward Ionel - September 9, 2021 - , , ,

Mirantis is proud to announce the release of Lens 5.2, bringing exciting updates to the popular open source integrated development environment (IDE) for Kubernetes. This release consists of several new and improved features, including Apple M1 chip support, a streamlined user experience when adding or removing clusters, Monaco editor integration, and more.  

Learn more about the new features and enhancements below, or see the full change log. Get started today!

Optimized for the Apple M1 Chip

In order to properly support the new Apple Silicon M1 Chip, we leveraged the electron-builder tool to build the new binaries. With Lens 5.2, we now ship separate versions of Electron for Intel Macs (x64) and Apple’s M1 hardware (arm64). This is critical to ensure that M1 chip users have a beautiful experience while using Lens IDE. With Lens now optimized for the new Apple Silicon chip, we are confident that M1 users will see improved performance and fewer bugs.

Add/Remove Clusters Effortlessly 

With every major release, Mirantis strives to improve Lens IDE for all Kubernetes users — and that means we rely on community feedback. The release of Lens 5 in June 2021 was by far the largest release since we open sourced the project back in March 2020, and it brought many UI/UX updates. After conducting several user surveys, we learned that adding and removing a cluster wasn’t optimized for the best experience. I’m proud to say that we have listened to your feedback and made significant improvements — users can now add and remove clusters with ease. 


  • Quick launch to add clusters directly from the Catalog.
  • UI guidance and hints regarding usage of kubesync for import/managing clusters from Kubeconfigs for more clarity of the feature.
  • Stabilize the ability to remove clusters by adding a new dialog that will guide the user when removing entries from their kubeconfig to increase clarity and ensure expected results.

Monaco Editor Integration

As always, making impactful enhancements to Lens is one of our top priorities. This is why we have taken the opportunity and necessary steps to integrate Monaco Editor into Lens IDE.   Monaco Editor is the code editor that powers VScode and has several features that will enhance our terminal capabilities. 


  • Delivers new possibilities for additional language support
  • Monaco Editor integration will improve the developer experience when working with Lens

Auto-Join Cluster Token

The Auto-Join Cluster Token feature was built to allow Kubernetes administrators the ability to onboard their clusters to Lens Spaces manually. This feature is ideal for businesses that can only access their clusters through a bastion or jump box.  Cluster administrators can now manually install the boreD agent to their cluster, allowing users the ability to access the cluster via Lens Spaces through a bastion host. 

Other Notable Changes

Lens 5.2 is an incremental release. Here’s a list of other changes that are visible to Lens users:

Notable features:

  • Made copying Kubernetes resource names from the UI easier
  • Added ability to rename hotbars
  • Namespace selector UX improvements
  • Metrics query improvements plus metrics added to namespaces and jobs

Notable bug fixes: 

  • Improved dashboard updates reflecting cluster changes in the nodes and crd views
  • Fixed metrics loading for some Kubernetes resources
  • Fixed font size variations in the Catalog sidebar
  • Updated bundled kubectl to v1.21.2 to improve port-forward connections
  • Limit hotbars to 12 slots

If You Missed Our Last Release

In June 2021, we released our most significant update to Lens IDE since we open sourced the project in March 2020. If you are unaware of Lens 5, I encourage you to read more below.  

Lens 5 improves collaboration and teamwork for anyone working with Kubernetes. We are lowering the barrier of entry for new users and improving productivity for experienced users. 

The highlights of Lens 5 are Catalog, Hotbars and the cherry on top: Spaces. If you’re interested in learning more about the features brought to Lens 5, you can read our former release blog here.
